CURRENT-COLLECTOR. surroar.

Application filed October 5, 1921. Serial No. 505,455.

To all whom it may concern Be it known that I, ELLIS S. LINCOLN. a citizen of Sweden, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Current-Collector Supports, of which the followingis a specification.

My invention. relates to a support for current collectors and particularly to that class of collectors used in the operation of trackless trolley systems where the bus or car is obliged to operate on either side of and to a considerable distance from the overhead conductors as well as in line therewith, and therefore the support for the collectors must make, at times, a considerable angle with the conductors without disturbing the engagement of the collector therewith. It is also desirable in trackless trolley operation tohave a positive and a negativeoverhead conductor as the wheels of the bus are insulated from the ground by rubber tires and this requires two collectors and in my invention I have provided means of mounting the two collectors on one support. My invention provides for means of yieldably main taining thedistance between the collectors at apredetermined distance apart and also when one collector is movedfrom its normal position the other collector is moved like-- wise.

In the accompanying drawing Fig. 1 is a top plan view of my invention.

Fig. 2 is a side elevation of my invention.

Fig. 3 is a top plan view of a modification of F 1g. 1., In my preferred form shown in Figs. 1 and 21 provide a pole 1 which may be of any length required and which is upwardly spring held by a trolley base secured to the lower end of pole land to the bus roof. I have not shown the base as they are common and well known and I am not bound to the use of any particular design. Adjacent the upper end of the pole 1'1 secure a head H which is arranged to rotate to a limited de gree relative to the pole 1. Secured to the head by means of the clevis members 3-3 are arms 4.--il', and to each arm 14:' is secured the current collecting member C. A bolt or pin 5 holds the, clevis to the head. Each clevis swivels relative to the head and the movement is limited by the set screw 6 engaging adjacent parts of the head. The head comprises a sleeve 7 secured to the pole 1 by means of a key 8. This sleeve is provided with a flange 9 provided with a slot 10.. The head H is also provided with a body 11 which is mounted to rotate on the sleeve but is limited in rotation by the tongue 12 projecting into the slot 10 and engaging the sides thereof. The body is held if; place on the sleeve by the threaded collar 1? I To the projecting end 14: of the pole 1 is mounted a slidable sleeve 15 and the two adjustable collars 16 and 16 which may be locked in position by the set screws 17. Mounted on the member 11 and between the sleeve and each collar is a spring 18 and 18 respectively which yieldingly hold the sleeve in a predetermined position under normal conditions and which position may be altered by changing the position of the collars 1616.as required. i

To each arm. 4+4 is secured a fixed sleeve 19, held by screws 20. and extending between each sleeve 19 and the sleeve 15 is a rigid member 21 pivotally secured to the sleeves 19 and 15.

It will be quite evident that if the arm 1 is moved in either direction. about the pin 5 that this motion will be transmitted through the bars 21-21 to the arm 4' causing it to move an equal amount and in the same direc tion with respect to the line of axis of the pole 1. If the stress moving the arm 4 is released and there is no stress holding the arm 4 then the springs 18 and 18 acting on thesleeve 15 will return the arms to their normal or predetermined posit-ion. By my invention the arms 1-a' are yieldingly maintained with each arm forming the same angle with the arris of the pole 1.

The modlfication shown in Fig. 3 is the same as the arrangementshown in Figs. 1 and 2 and the construction is quite similar, the exception being the pivoting of the members 21 to the clevis members 3-3.

Having described and shown my invention I claim 1. A supportingarm as described, two auxiliary arms pivotally mounted thereon each to receive a current collector and move toward or away from each other in the same plane about the pivotal point and means yieldably holding the auxiliary arms in a predetermined position.
